During World War One, Essex Regiment had 17
battalions but these did not fight as one unit as they were
split across the army. The exception to this was the Territorial
battalions who were posted to Turkey and Egypt for the duration
of the war, fighting as 161 Brigade.

The table below shows the Division and Brigade
